WINDOW-VENTILATOR.

Specification of Letters Patent. Patented Sept, '7, 1969,

Application filed September 23, 1908. Serial No. 454,369.

To alt-whom itmay concern.- I

Ventilators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates tocertain new and :useful improvements in ventilators, and is;

designed to provide a device of the class deapplied to a window, or similar structure, and preferably at the top thereof, and which can be adjusted 5 to admit and direct toward the ceiling airj from the external atmosphere and prevent the possibility of a direct draft striking the j occupants of, the room.

Essentially my invention contemplates the employment of an auxiliary frame which is: adapted to carry a screen and a shutter, both of the latter being independently movable of each other so that if for any reason it is desired to utilize the screen conjunctively with or without the shutter the same may be attained in a facile manner. L y

With these and other objects 1n view, the

preferred embodiment of my invention resides in that construction and arrangement illustrated in the accompanying drawings, and embraced within the scope of the appended claims.

In said drawings :Figure I is a front elevation of the upper portion of a window showing the adaptation of my improvement. Fig. II is a central vertical section thereof. Figs. III and IV are central vertical sections of a door showing the application of the invention, the views being in reverse relation to each other in order to clearly illustrate the manner of mounting the screen and shutter. Figs. V and VI are perspective views, respectively, of the screen connecting link and the shutter connecting link as illustrated in Figs. IV and V of the drawings.

Referring more particularly to the drawings for a detail description of my invention the numeral 5 designates an ordinary type of window having interposed at the upper portion thereof and permanently secured thereto, an auxiliary frame (6) with .an opening (7) for ventilation purposes. Adjacent the upper terminal of said auxiliary frame (6), as clearly exhibited in Fig. II of the drawings, is a transversely extending rod Be it known that I, VVILLI AM I I; DEAN,,

shutter 9) and a screen (10), the same being maintained in a normally and outwardly swung position by the coil spring (11), the lower distal ends of said shutter and screen having eyelets (12) to which are suitably attached the operating cords (18) and (14), the latter passin from said points of connection through tie aperture or channel (15) in the lower part of said auxiliary frame and thence a suitable distance so that it may be readily accessible. The base of the frame .(6) is cut away, asat (15 to accommodate the lower end portions of the shutter and screen. It will thus be seen by this arrangement that the shutter and screen may be simultaneously opened or closed by the appropriate manipulation of the cord (13) the screen being operated independently by the sorely-(14).; In Figs. III and IV the same principle of my invention is involved, the only deviation being that the said shutters and screens are mounted on opposite sides of the frame (6), as at 16 and 17, and each actuated by the coil springs (17 the said frame being incorporated as a part of a door, as indicated by the numeral 18, the base portion of the frame being rabbeted, as at 19 and 20, to receive the respective end portions of the shutter ,and screen. To provide for this change it will be noted that the channel (15) as shown in Fig. II of the drawings and the eyelets (12) of the shutter and screen have "been dispensed with and in lieu thereof, I

employ an angular crank lever (21'), illustrated .in detail in Fig. VI which is pivoted on the outside of the frame portion proximate the upper end thereof, as at 22, one terminal thereof being provided with an eyelet for connection with the operating chain, cord, or the like (24), the other terminal (25) being designed to freely engage the inner side of the shutter (9) and cause the same to oscillate from a closed to an open position, or vice versa, when the said cord is operated.

Referring particularly to Figs. IV and V it will be observed that the screen lever (26) is preferably formed as an integral part of the transversely extending rod (11**) upon which the said screen swings, being rearwardly and downwardly bent in substantially rightangularly contour and having its distal end which is secured to the operating cord (28), the latter passing over the guide pulley (29),

(18) upon which are pivotally mounted a provided with an eyelet 27),

carried by the inner side of the door frame. It will be understood, of course that the shutter-operating lever 21 and the screenoperating lever 26 are disposed at opposite ends of the frame 6. Outside of the structure whether it be a door, or a window I mount a hood (30).

In practical use a constant current of fresh air is provided throughout the room without the irregular drafts and currents attendant upon open doors and Windows, the means usually relied upon for ventilation, and at the same time the screen precludes the entrance of insects, foreign particles, and the like.

My invention is simple in operation, economical to install, and may be utilized with facility and with eflicacious results.

Having thus described my invention, What I claim, is

1. A ventilator for doors and Windows, comprising a frame, pivot rods carried thereby and disposed opposite each other, a shutter carried by one rod, a screen carried by the other rod, means for normally retaining said screen and shutter in open positions, and means for closing the same.

2. A ventilator for doors and windows, comprising a frame, a shutter pivotally mounted in said frame, a screen also pivotally mounted in the frame, independent means for normally swinging said shutter and screen in opposite directions to open the same, and independent means for closing the shutter and screen.

3. A device of the character described, comprising a ventilating frame and a weather hood, rods mounted on opposite sides of said frame, a shutter and screen carried by the respective rods, springs for maintaining the shutter and screen normally open, and means for closing the shutter and screen.

4. A device of the character described, comprising a ventilating frame and a weather hood, rods mounted on opposite sides of said frame, a shutter and screen carried by the respective rods, springs for maintaining the shutter and screen normally open, a crank arm formed integrally with the screen rod, a lever pivoted to said frame and having an angular deflected terminal for engagement with the shutter rod, and operating cords connected to said arm and lever.

In testimony whereof I hereunto aflix my 55 signature in presence of two witnesses.
